Made in the USA, the Milwaukee® Hole Dozer™ Hole Sawfeatures Rip Guard™, the strongest tooth form in the industry, backed by the Rip Guard™ Limited Lifetime Tooth Break Warranty. Each tooth is built with more steel behind the cutting edge for added strength. The Rip Guard™ warranty on tooth breaks is a first for the hole saw industry. The added tooth strength along with 8% cobalt give added life to the teeth, allowing for increased productivity on the jobsite, as well as continued hole quality. The Hole Dozer™ includes Plug Jack™, an all access slot design that allows for full access during plug removal. The Plug Jack™ gives access lower into the cup for thick material and higher towards the teeth for thin material. With multiple positions to apply leverage and better plug access, Plug Jack™ increases productivity and eliminates wasted downtime between holes.For fast, tool-free change-outs, use Milwaukee's universal Quick-Change Arbors. 49-56-7210, 49-56-7240, 49-56-7250, and 49-56-9100.
